1. MOVING YOUR FREEZER
The refrigeration system of the cabinet is designed to
operate with the cabinet located on a flat surface. Do not
tilt the cabinet more than 30  to any side. If the cabinet
must be tilted on an angle for handling or moving purposes
allow it to sit in an upright position for at least two (2) hours
prior to starting.
2. SAFETY PRECAUTIONS
In this manual, the words WARNING and CAUTION mean
the following:
*WARNING: a potentially hazardous situation, which if not
avoided, could result in serious injury or death.
*CAUTION: a potentially hazardous situation, which if not
avoided, may result in minor or moderate injury or damage
to equipment.
Before installing, using or maintaining this product, please
be sure to read this manual carefully. Failure to follow these
instructions may cause this product to malfunction, which
could result in injury or damage.
Below are important safety precautions that apply to this
product:
•Use this product only in the manner described in the
product literature and in this manual. Before using it,
verify that this product is suitable for its intended use.
•Do not modify system components.
•The cabinet must be properly grounded in conformity
with national and local electrical codes. Never
connect the unit to overloaded power sources.
•Disconnect the unit from all power sources before
cleaning, troubleshooting or performing other
maintenance on the cabinet.
3. CHOOSING A LOCATION
3.1 Air Circulation
The cabinet should be situated to allow proper air circulation
in a well ventilated room. Provide at least 3” of space around
the freezer for ventilation. Avoid placing the freezer in
locations exposed to direct sunlight, heat registers or any
other heat sources.
*NOTE: The cabinet must be installed on a sturdy, solid,
level surface resting firmly on all four mounting points.
3.2 Ambient Temperature
Do not place cabinet in sunlight, near heating diffusers,
radiators or other sources of heat. Drafts from fans, air
conditioning or open doors can also affect the product
temperature. The ambient temperature range at the location
must be 59 to 90F (15 to 32C).
*Warning: This unit is not a “rapid-freeze” device.
Freezing large quantities of liquid or high water content
items will temporarily increase the compressors to operate
for prolonged periods of time. Attempting to utilize this
freezer improperly may jeopardize safety or cause undue
stress or damage to the refrigeration compressors.
Avoid opening the door for extended periods of time since
chamber air will escape rapidly. Room air, which is higher
in humidity, will replace chamber air and may cause frost to
develop in the chamber more rapidly.
Before you get started, please take a few minutes
to read through this manual.

4. CHECK OUT YOUR NEW FREEZER
4.1 Lid Seal
The gasket on the door has a magnetic strip to help door seal.
Be sure to keep the gasket clean and free of debris. Clean
any frost that may build up. If the gasket does not seal
properly, the freezer may experience problems with
maintaining temperature and excessive frost build up.
4.2 Interior Compartment Temperature
The temperature is controlled by a CAL 9500 digital
temperature controller. When you first power up the freezer,
the high stage compressor and fan will start and operate for 3
to 6 minutes before the low stage compressor starts. Pull
down to minimum temperature will take from 3 to 6 hours,
depending on ambient temperature and size of cabinet. The
high stage compressor runs 100% of the time. The low stage
compressor will cycle on and off to maintain the temperature
of the controller setting. Set the control to the desired set
point. To view the set point temperature, press the * and the
UP arrow keys together. To decrease the set point
temperature, press the * and the DOWN arrows keys
together.
Freezers are shipped from the factory with the indicating
digital control programmed for proper operation. All but the
temperature settings may be adjusted. The temperature
sensor is a type “T” thermocouple located on the side wall of
the inner-liner.
4.3 Alarm
The Alarm should be kept in the “OFF” position until the
cabinet temperature has reached the appropriate setting.
When the temperature has been reached, the temperature
alarm should be switched to the “ON” position and is now
ready to operate.
The Alarm is equipped with a time delay relay to prevent the
alarm from going off every time the door is opened. This
relay can be adjusted from 1 to 10 minutes. This delay is
factory set for 10 minutes.
To adjust time delay relay:
a) Remove screw located on right side, middle of
instrument panel with temperature controller.
Instrument panel will hinge open. Time delay has a
dial and is located on lower right corner of electric
box.
b) If you have a chart recorder: Open glass door to get
to the black instrument panel with chart recorder.
Remove screw located on right side, middle of
panel. Instrument panel will hinge open. Time delay
has a dial and is located on lower right corner of
electric box.
NOTE: It is recommended to keep the freezer operating
continually rather than turning the freezer off and on.
4.4 Chart Recorder (Optional )
If your freezer has a chart recorder installed. On initial start
up you must replace the round paper chart, connect the 9 volt
battery and remove the black rubber cap on pen.
WARNING: Do not lift the pen arm in order to slide a new
chart under the pen or to remove the black rubber cap.
To replace the paper chart: Press and hold the “change chart”
button (#3) for approximately one second until pen begins to
move to the left of the chart and then release the button. Wait
until the pen has moved completely off the chart paper. To
remove the chart paper, unscrew (counter-clockwise) the
knob at the center of the chart paper. Remove old paper and
position new one so that the correct time line coincides with
the time line groove on the chart plate. Re-attach the knob,
screw securely (by hand). (Do not over tighten. Over
tightening can damage the gears in the chart motor gearbox
assembly.) Press and hold change chart button (#3) again
until pen begins to move back and then release button.
To remove the black rubber cap at start up: While you have
arm moved off the paper for changing the chart, remove the
rubber cap.
5 ELECTRICAL CONNECTIONS
5.1 Wiring
This cabinet is equipped with a three-prong (grounding) plug
for your protection against shock hazards. The cabinet
should be plugged directly into a properly grounded three-
prong receptacle.
Where a two-prong wall receptacle is encountered, it must be
replaced in accordance with the National Electronic Code
and local codes and ordinances. A licensed electrician must
do the work.
The electrical outlet should not be controlled by a wall
switch, which might be turned off accidentally.
*WARNING: Do NOT under any circumstances cut or
remove the round grounding prong from the cabinet
plug.
*CAUTION: For personal safety and trouble-free operation,
this cabinet must be properly grounded before it is used.
Failure to ground the equipment may cause personal injury
or damage to the equipment. Always conform to the

National Electrical Code and local codes. Do not plug in the
cabinet to overloaded power lines.
Consult a licensed electrician if you have ANY doubt
about the grounding of your wall receptacle. Only a
licensed electrician can determine the polarization of
your wall receptacle.
6 DANGERS OF A LOW TEMPERATURE FREEZER
Any temperature below 0Centigrade or 32Fahrenheit
provides a potential condition to cause freezing of water or
material containing water. Material containing water
solutions of salt or sugar will freeze at a slightly lower
temperature, depending on the content of the solution.
Because all warm-blooded creatures are composed of a great
percent of water with salinity, they are subject to freezing
whenever the body cells, parts or extremities reach
temperatures below freezing.
6.1 When Skin Freezes
When your skin is exposed to subfreezing temperatures for
an extended amount of time, it can freeze. Your blood
vessels constrict in response to dropping temperatures. This
reduces the flow of blood and, therefore, the amount of
oxygen to the tissues. When water in these tissues freezes
and forms ice crystals, cell structure is destroyed.
Tissue damage from cell death interrupts circulation in the
smallest blood vessels. Blood clots form and blood flow is
further diverted away from the frozen tissue. At this point,
your skin temperature drops and the injured area grow even
colder.
The first sign of frostbite may be a slightly painful tingling
sensation, which often is followed by numbness. Your skin
may look pale, and feel hard, cold and numb.
In the event of frostbite, warming is vital. Carefully warm
frost bitten areas gradually. Place your hands directly on the
skin of warmer areas of your body. If possible, immerse
your hands in water that is slightly above normal body
temperature (about 100F or 37.8C), or which feels warm to
someone else, until your normal color returns. Do not use
direct heat. Seek medical attention as quickly as you can.
7 REFRIGERATION COMPARTMENT
The refrigeration system of a Scientemp freezer is
hermetically sealed. It requires no maintenance. However, in
areas where excessive dust and dirt collects, the condenser
must be kept clean. To clean the condenser, remove power to
freezer. Refer to instruction sheet in this packet on how to
get to the condenser. If you need another copy, one can be
found and downloaded on our website. You can also contact
us and we can email you one.
7.1 Fan
The fan motor has lifetime lubrication. It requires no
maintenance.
7.2 Frost removal
1. While the freezer is running the frost may be
removed with a plastic or wooden scraper or
spatula. Do not use metal or sharp objects such as
an ice pick, as this will cause serious damage to the
finish of the inner-liner of the freezer. The frost and
ice may be collected in a pan, towel or any device to
prevent it from falling to the bottom of the freezer
or onto the material stored in the freezer. Most of
the frost and ice collects near the top edge and is
easily removed.
2. In the case where the freezer is not loaded, frost and
ice may be removed by disconnecting the power
until the frost and ice thaw. After defrosting, dry
the freezer compartment interior and plug freezer
back in.
*CAUTION: Wear protective clothing while either
handling or coming in contact with inside of freezer.
Hands should be dry and protected by using gloves.
Insulated gloves are best for extended use when
handling frozen product. Sleeves or arm-length
insulated gloves should protect arms. Coats,
insulated aprons, etc. should protect other parts of
the body that may be exposed to the cold.
